Can a genome test help in my breast cancer treatment at 52?

Question

Hello doctor,

I was recently diagnosed with stage 2 breast cancer, and my oncologist mentioned that genomic testing of my tumor could help determine the most effective treatment plan for my specific cancer. My mother had breast cancer at 52 years of age, and my aunt had ovarian cancer, so I am wondering if there is a hereditary genetic component to my diagnosis. I want to make sure I am getting the most targeted and personalized treatment possible, rather than a one-size-fits-all approach. I am also concerned about whether this genetic information might indicate increased cancer risk for my two daughters.

How does cancer genome testing work?
What information does it provide?
How will it help guide my treatment decisions and surgery options?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

I completely understand your worries about this diagnosis, but I want to reassure you that we now have many treatment options available, especially when cancer is identified and treated at an early stage.

Genetic testing is an important part of the evaluation because it can help estimate your risk and guide treatment decisions. The results generally fall into three broad categories.

A low-risk result may mean that chemotherapy is less likely to provide additional benefit, and treatment may focus on surgery and hormonal therapy.
An intermediate-risk result may lead doctors to consider a combination of treatments such as chemotherapy, radiotherapy, and hormonal therapy, while also providing information that may help guide future treatment choices if the cancer were ever to return.
A high-risk result can influence treatment planning more significantly. In some situations, particularly when there is a strong family history of breast or ovarian cancer, doctors may discuss preventive options such as bilateral mastectomy and oophorectomy to reduce future cancer risk.

For your daughters, you may also choose genetic testing using a blood or saliva sample. This can help clarify whether they carry an inherited cancer-related mutation and assist in planning appropriate screening.

For women under 35 years of age, doctors may recommend regular breast self-examination and periodic clinical evaluation, with ultrasound used when indicated. For women over 35 years of age, yearly mammography and routine check-ups are commonly advised.

You also can opt for genomic or genetic testing, as recommended by the oncology team.

The possible treatment plan for you will be,

Chemotherapy.
Surgery.
Radiotherapy.
Hormonal therapy.

Preventive measures that can be taken in your case are

If you are a high-risk individual, preventive surgery such as a bilateral mastectomy.
Oophorectomy may be discussed as part of a long-term risk-reduction strategy.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
